I have purchased a Nexus 7 and have spent weeks working with it, I finally learned all the ins and outs of rooting and what to and not to do. Everything was all set up perfectly until I loaded it up a few days ago and theres all this bs on the main window like "slots" "live lens" "expedia" Candy Crush" all this "bloat/adware which I never installed. How can I rid of ti for good and prevent this from happening again. Any help is greatly appreciated. On a scaled of 1-100 im about at 85 with android knowledge if that helps. please help someone in need, thanks guys.
